  • Circumlunar flight using Gemini seriously studied - . Nation: USA. Related Persons: Webb. Program: Apollo. Spacecraft: Gemini. During a news conference, Kenneth S. Kleinknecht, Deputy Manager of the Gemini Project Office at MSC, affirmed that, although no firm decisions had yet been made, the concept of a circumlunar flight using a Gemini spacecraft was being seriously studied. The mission would use Titan II and III-C launch vehicles and would require rendezvousing in earth orbit. NASA, Martin-Marietta Corporation (builder of the Titan), and Aerojet-General Corporation (which manufactured upper stages for the III-C) all were studying the feasibility of such a flight. Later in the year, NASA Administrator James E. Webb eliminated the possibility of a Gemini circumlunar mission, ". . . our main reliance for operating at lunar distances . . . is the large Saturn V/Apollo system."

  • Malfunction caused Apollo boilerplate 1 to impact on land - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. At North American's drop facility, a malfunction in the release mechanism caused boilerplate 1 to impact on land rather than water. After a recurrence of this accident on August 6, a team of investigators began looking into the problem. Drops were suspended pending their findings. These incidents aggravated delays in the test program, which already was seven weeks behind schedule.

  • Soyuz hatch problem - . Nation: USSR. Related Persons: Sharafutdinov; Shcheglov; Skvortsov; Komarov; Khrunov; Gorbatko; Mishin; Tsybin; Severin; Alekseyev, Semyon; Anokhin; Yeliseyev; Smirnov. Program: Soyuz. Flight: Soyuz 1; Soyuz 2A; Soyuz s/n 3/4. Spacecraft: Soyuz 7K-OK; Yastreb. Training of the new cosmonaut cadre is reviewed. English language courses are proving to be a particular problem. There have been some potential washouts - Sharafutdinov has done poorly in astronomy, Shcheglov suffered an injury at the beach, Skvortsov damaged his landing gear on a MiG-21 flight.

    At 15:00 a major review is conducted, with Komarov, Khrunov, Gorbatko, Kamanin, and other VVS officer meeting with OKB-1 leaders Mishin, Tsybin, Severin, Alekseyev, Anokhin, and other engineers. Film is shown of the difficulties in the zero-G aircraft of cosmonauts attempting to exit from the 660 mm diameter hatch. In four sets of ten attempts, the cosmonaut was only to get out of the hatch half the time, and then only with acrobatic contortions - the inflated suit has a diameter of 650 mm, only 10 mm less than the hatch. Mishin finally concedes the point. But installation of the hatch in Soyuz s/n 3 and 4 is not possible - the spacecraft are essentially complete, and to add the hatch would delay their flight 6 to 8 months. Then Mishin makes the astounding assertion that Gorbatko and Khrunov are not adequately trained to be engineer-cosmonauts, and without this he will not allow them into space. He suggests OKB-1 engineers Anokhin and Yeliseyev instead. After outraged response, Severin finally sinks this suggestion by pointing out that no space suit has been prepared for Anokhin, and that it will take two to three months to make one. Kamanin is astounded that Mishin has pushed Anokhin all the way up to Smirnov and the VPK without even knowing he could not possibly fly due to this restriction. It again points out their poor management. Finally Mishin agrees that spacecraft s/n 5 and 6 and on will have 720 mm hatches. The ECS for the suits for those missions will have to be changed from a backpack configuration, with the equipment rearranged around the waist of the cosmonaut. The crews for the flight will be an experienced VVS pilot cosmonaut as commander, and (Kamanin realizes he may have to concede) a VVS engineer as flight engineer cosmonaut. They will have to complete training by 1 October 1966.

Nation: USA. Related Persons: Irwin; Scott; Worden; Brand; Gordon; Schmitt. Agency: NASA Houston. Program: Apollo. Class: Moon. Type: Manned lunar spacecraft. Flight: Apollo 15. Spacecraft: Apollo CSM. Duration: 12.30 days. Decay Date: 1971-08-07 . USAF Sat Cat: 5351 . COSPAR: 1971-063A. Apogee: 169 km (105 mi). Perigee: 166 km (103 mi). Inclination: 29.6800 deg. Period: 87.84 min. Apollo 15 (AS-510) with astronauts David R. Scott, Alfred M. Worden, and James B. Irwin aboard was launched from Pad A, Launch Complex 39, KSC, at 9:34 a.m. EDT July 26. The spacecraft and S-IVB combination was placed in an earth parking orbit 11 minutes 44 seconds after liftoff. Activities during earth orbit and translunar injection (insertion into the trajectory for the moon) were similar to those of previous lunar landing missions. Translunar injection was at about 12:30 p.m., with separation of the CSM from the LM/S-IVB/IU at 12:56 p.m. At 1:08 p.m., onboard color TV showed the docking of the CSM with the LM.

    S-IVB auxiliary propulsion system burns sent the S-IVB/IU stages toward the moon, where they impacted the lunar surface at 4:59 p.m. EDT July 29. The point of impact was 188 kilometers northeast of the Apollo 14 landing site and 355 kilometers northeast of the Apollo 12 site. The impact was detected by both the Apollo 12 and Apollo 14 seismometers, left on the moon in November 1969 and February 1971.

    After the translunar coast, during which TV pictures of the CSM and LM interiors were shown and the LM communications and other systems were checked, Apollo 15 entered lunar orbit at 4:06 p.m. EDT July 29.

    The LM-10 Falcon, with astronauts Scott and Irwin aboard, undocked and separated from the Endeavor (CSM 112) with astronaut Worden aboard. At 6:16 p.m. EDT July 30, the Falcon landed in the Hadley-Apennine region of the moon 600 meters north-northwest of the proposed target. About two hours later, following cabin depressurization, Scott performed a 33-minute standup EVA in the upper hatch of the LM, during which he described and photographed the landing site.

    The first crew EVA on the lunar surface began at 9:04 a.m. July 31. The crew collected and stowed a contingency sample, unpacked the ALSEP and other experiments, and prepared the lunar roving vehicle (LRV) for operations. Some problems were encountered in the deployment and checkout of the LRV, used for the first time, but they were quickly resolved. The first EVA traverse was to the Apennine mountain front, after which the ALSEP was deployed and activated, and one probe of a Heat Flow experiment was emplaced. A second probe was not emplaced until EVA-2 because of drilling difficulties. The first EVA lasted 6 hours 33 minutes.

    At 7:49 a.m. EDT August 1, the second EVA began. The astronauts made a maintenance check on the LRV and then began the second planned traverse of the mission. On completion of the traverse, Scott and Irwin completed the placement of heat flow experiment probes, collected a core sample, and deployed the American flag. They then stowed the sample container and the film in the LM, completing a second EVA of 7 hours 12 minutes.

    The third EVA began at 4:52 a.m. August 2, included another traverse, and ended 4 hours 50 minutes later, for a total Apollo 15 lunar surface EVA time of 18 hours 35 minutes.

    While the lunar module was on the moon, astronaut Worden completed 34 lunar orbits in the CSM operating scientific instrument module experiments and cameras to obtain data concerning the lunar surface and environment. X-ray spectrometer data indicated richer abundance of aluminum in the highlands, especially on the far side, but greater concentrations of magnesium in the maria.

    Liftoff of the ascent stage of the LM, the first one to be televised, occurred at 1:11 p.m. EDT August 2. About two hours later the LM and CSM rendezvoused and docked, and film, equipment, and 77 kilograms of lunar samples were transferred from the LM to the CSM. The ascent stage was jettisoned and hit the lunar surface at 11:04 p.m. EDT August 2. Its impact was recorded by the Apollo 12, Apollo 14, and Apollo 15 seismometers, left on the moon during those missions. Before leaving the lunar orbit, the spacecraft deployed a subsatellite, at 4:13 p.m. August 4, in an orbit of 141.3 by 102 kilometers. The satellite would measure interplanetary and earth magnetic fields near the moon. It also carried charged-particle sensors and equipment to detect variations in lunar gravity caused by mascons (mass concentrations).

    A transearth injection maneuver at 5:23 p.m. August 4 put the CSM on an earth trajectory. During the transearth coast, astronaut Worden performed an inflight EVA beginning at 11:32 a.m. August 5 and lasting for 38 minutes 12 seconds. He made three trips to the scientific instrument module (SIM) bay of the SM, twice to retrieve cassettes and once to observe the condition of the instruments in the SIM bay.

  • Mir News 182: Ham-work during successfully accomplished Altair mission - . Nation: Russia. Program: Mir. Flight: Mir EO-14. Jean-Pierre, F6Mir, was an enthusiastic and skilled amateur. In this field he did not yield to Tognini during his flight in 1992. H. made all his QSO-s in the proper way and during the last day of his flight he told in a CQ-message that he had been pleased by radio-amateurism and he expressed his gratitude to all amateurs with whom he had been in contact. He was not pleased about an Italian amateur, who, using a very strong signal, often blocked the uplink too long. He limited H's possibilities to make more QSO-s with French and other amateurs.

    Mir-crews: On 16.7.93 the control over the Mir-station had been transferred to the new crew: Tsibliyev took care of the attitude control and Serebrov had replaced Polishchuk as board-engineer. Manakov and Polishchuk prepared their return flight. Their main concern was to find room in Soyuz-TM16 for all what they had to bring back to earth. Thoroughly they checked the on board systems of that ship and rehearsed the procedures for the navigation during and after the undocking from Mir on 22.07.93. A physician at TsUP regularly checked the health of M. and P.

    New crew: As of 22.07.93 Tsibliyev and Serebrov are working strenuously. They are busy with a lot of important repairs and replacements. Obviously they have to solve all problems with the attitude(movements-) control of the complex. (Gyrodynes and the VDU motor in the Sofora-girder). They already work on the Gyrodynes. It is a pleasure to hear the new crew: undoubtedly excellent cosmonauts. Quite normal for S.: this is his 4th flight, but the novice T. acts as if he has a long experience in space.

    Progress-M18 and M19: Recently the decay of the first freighter (M18) still was on schedule for 24.07.93. This has been put back. Though still not for 100% sure the plan is to undock Progress-M18 on 8.08.93 after the launch that same day of Progress-M19. If this happens it will be a novelty: for a while 2 freighters flying autonomously in space.

Inclination: 51.6000 deg. Period: 91.20 min. Return to flight after loss of Columbia. Delayed extensively as NASA attempted to fix the external tank foam-shedding problem that resulted in the loss of Columbia (first planned for September 12, 2004, the launch slipped to March; May 14, 15 and 22; July 13, 2005). Discovery safely reached orbit at a total mass of 121,485 kg, but extensive video coverage detected external tank foam shedding during ascent. Discovery docked at the Pirs module of the ISS on 28 July 28 at 11:18 GMT. Following replenishment of the station (using the Raffaello MPLM-6 module with 8240 kg of supplies), a series of spacewalks verified the integrity of the shuttle's heat shield and tested repair techniques, Discovery undocked from the ISS at 07:24 GMT on 6 August and landed safely on Runway 22 at Edwards Air Force Base at 12:11 GMT on 9 August. However the shuttle fleet was immediately grounded again while NASA attempted to find a permanent fix to the external tank foam woes.
